Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of thunderbird installed on the remote host is prior to 78.7.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1603 advisory.

 - When a HTTPS pages was embedded in a HTTP page, and there was a service worker registered for the former, the service worker could have intercepted the request for the secure page despite the iframe not being a secure context due to the (insecure) framing. This vulnerability affects Firefox < 84. (CVE-2020-26976)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
